Method Detail
isInitialized
public boolean isInitialized()
Description copied from interface:MessageLiteOrBuilderReturns true if all required fields in the message and all embedded messages are set, false otherwise.- Specified by:
isInitializedin interfaceMessageLiteOrBuilder
findInitializationErrors
public java.util.List<java.lang.String> findInitializationErrors()
Description copied from interface:MessageOrBuilderReturns a list of field paths (e.g. "foo.bar.baz") of required fields which are not set in this message. You should callMessageLiteOrBuilder.isInitialized()first to check if there are any missing fields, as that method is likely to be much faster than this one even when the message is fully-initialized.- Specified by:
findInitializationErrorsin interfaceMessageOrBuilder
getInitializationErrorString
public java.lang.String getInitializationErrorString()
Description copied from interface:MessageOrBuilderReturns a comma-delimited list of required fields which are not set in this message object. You should callMessageLiteOrBuilder.isInitialized()first to check if there are any missing fields, as that method is likely to be much faster than this one even when the message is fully-initialized.- Specified by:
getInitializationErrorStringin interfaceMessageOrBuilder
hasOneof
public boolean hasOneof(Descriptors.OneofDescriptor oneof)
- Specified by:
hasOneofin interfaceMessageOrBuilder
getOneofFieldDescriptor
public Descriptors.FieldDescriptor getOneofFieldDescriptor(Descriptors.OneofDescriptor oneof)
- Specified by:
getOneofFieldDescriptorin interfaceMessageOrBuilder
toString
public final java.lang.String toString()
Description copied from interface:MessageConverts the message to a string in protocol buffer text format. This is just a trivial wrapper aroundTextFormat.Printer.printToString(MessageOrBuilder).
writeTo
public void writeTo(CodedOutputStream output) throws java.io.IOException
Description copied from interface:MessageLiteSerializes the message and writes it tooutput. This does not flush or close the stream.- Specified by:
writeToin interfaceMessageLite- Throws:
java.io.IOException
getSerializedSize
public int getSerializedSize()
Description copied from interface:MessageLiteGet the number of bytes required to encode this message. The result is only computed on the first call and memoized after that.- Specified by:
getSerializedSizein interfaceMessageLite
equals
public boolean equals(java.lang.Object other)
Description copied from interface:MessageCompares the specified object with this message for equality. Returnstrueif the given object is a message of the same type (as defined bygetDescriptorForType()) and has identical values for all of its fields. Subclasses must implement this; inheritingObject.equals()is incorrect.
hashCode
public int hashCode()
Description copied from interface:MessageReturns the hash code value for this message. The hash code of a message should mix the message's type (object identity of the descriptor) with its contents (known and unknown field values). Subclasses must implement this; inheritingObject.hashCode()is incorrect.
